Yes, I've seen some glitches if a lot of redrawing is happening that's 
with an Radeon R5 230.

The default acceleration method recently has changed from exa to glamor 
for this card as the radeonsi driver is now enabled as of 31st January.

Setting AccelMethod to exa restores the old behavior.

I'll recheck if time allows with a newer card (R7 240) which requires 
glamor as acceleration method.
